The data rate was demonstrated using pulsed amplitude modulation (PAM) with 4 or 8 levels. A discrete multitone modulation can be applied to the device for data transmission of 112 Gbps over 100 m of multimode fiber.

With duo binary 4-PAM modulation technology, a maximum data rate of 160 or 150 Gbps over 100 m of multimode fiber using multimode VCSELs has been demonstrated.
